In tho construction of locomotive ballio Walls heretofore, it has beencommon either to use very long fire-brick extending arross a number ofthese supporting tubes, or else use a plurality of separate bricks whichwere placed entirely above the tubes and were mutually dependent uponoavh other for Support, against. lateral tlisplaoeinont, and insoinucasss were dependent upon 0::(lk nther for support against \Pi'lfal (llfrlirltlt'ttmerit.

As illustiatedin Fig. lg-thesupporting; tubes '3 are fpreferably made parallel, so that bricks ouniform length may be used from one end of the furnace to the other. Asit would be practically impossibleto make the tubes 3 parallel from endto end becauseofinterference with the staybolts in the ends of thefire-box, the pre- 10'.ferred method of construction will be to inakeonly those portions ,ef the tubes 3 "arallel which lsupport the firebrick, Ee'ndingthe other ends of the tubes 3 lat-- erally as much as isnecessary to clear the 1L5 stay -boltsxir the front end of the firebox.

It'will be seen from the foregoing that .all th'ejbricks' composing thebattle wallare seituredag ainst lateral displacement independent ofeach. other, thatthese bricks are of such small size thati'they may beeasily handled, andlthat the-construction of the ends ofthe bricksprevent fusing together, so that jtlie'fbricks maybe easily removed whennecessary.

Another advantage of the construction re- I sides mfthe fact: that thebricks serve to 'cethe tubes themselves and prevent their ateial'movement. The tubes by reason of the-bricks fitting between them, notonly renforce each other, but are also braced from he sideplate's of thefire box by the outside ybricks'f). I

' 'A slightly -difierent form of brick L is ustrated in Figure 5. Thisstyle of brick ,-'Bf'5 fiias its endswhich fit the tubes cut away'in aslightly different manner, the construction an other respects beingsubstantially that illustrated in the arrangement heretofore :,describedIt will. be obvious that the ends 5:0;of'the'br1cks might? be cut awayin a number. -.o'f dliferent waysall coming within the scope J oftheinvent-ion, it only being necessary that the corner be so constructedthat the bricks can fit down between two adjacent tubes in 4 such amanner thatlateral displacement of the brick is guardediiagainst.

g. t;-Having thus described our invention and illustrated its use, whatwe claim as new and :desire ,to secure by Letters Patent is the followinY -fimomotive fire-box comprising in combination, side plates,longitudinally extending forwardly and downwardly inclined ation tubesbetween the side plates,

' circul of bricks upon the tubes-socketed at ,thei lower side' edges sothat their lower portions fit down'between the tubes, and a row go'fbricks extending from each .of the outside-tubes, to the adjacent sideplate,

69 siich-bricks being socketed at their lower inside/"edges to engagethe tubes at their upper Witnesses and outer side portions and beingupwardly inclined from their inner to their outer s des 'with theirouter edges resting against the side plates.

2. A locomotive fire-box comprising in combination, side plates,longitudinally extending forwardly and downwardly inclined circulationtubes between the side plate, rows of bricks supported upon'the tubes,and a 70 row of bricks extending from each of the outside tubes to theadjacent side plate, such bricks beingv socketed at their lower insideedges to engage the tubes at their upper and outer side portions andbeing upwardly inclined from their inner to their outer sides with theirouter edges resting against th side plates.
